Patent number: 7601646Abstract: Manufacturing yield of integrated circuits having differentiated areas such as array and support areas of a memory is improved by reducing height/step height difference between structures in the respective differentiated areas and is particularly effective in conjunction with top-oxide-early (TOE) and top-oxide-late processes. A novel planarization technique avoids damage of active devices, isolation structures and the like due to scratching, chipping or dishing which is particularly effective to improve manufacturing yield using TON processes and also using TOE and TOL processes when average height/step height is substantially equalized. Alternative mask materials such as polysilicon may also be used to simplify and/or improve control of processes.Type: GrantFiled: July 21, 2004Date of Patent: October 13, 2009Assignee: International Business Machines CorporationInventors: Deok-kee Kim, Ramachandra Divakaruni, Hiroyuki Akatsu, George Worth, Jay Strane, Byeong Kim

Patent number: 7595010Abstract: Adding at least one non-silicon precursor (such as a germanium precursor, a carbon precursor, etc.) during formation of a silicon nitride, silicon oxide, silicon oxynitride or silicon carbide film improves the deposition rate and/or makes possible tuning of properties of the film, such as tuning of the stress of the film. Also, in a doped silicon oxide or doped silicon nitride or other doped structure, the presence of the dopant may be used for measuring a signal associated with the dopant, as an etch-stop or otherwise for achieving control during etching.Type: GrantFiled: October 26, 2007Date of Patent: September 29, 2009Assignee: International Business Machines CorporationInventors: Ashima B.

Patent number: 7583065Abstract: An active linear regulator circuit in parallel with a filter capacitor of a switching voltage regulator injects current to a load only when the switching regulator and capacitor cannot supply adequate current to follow high frequency load transients in a manner which is compatible with adaptive voltage positioning (AVP) requirements. control of current injection and determination of the insufficiency of current from the switching regulator and capacitors is achieved by impedance matching of the linear regulator to the switching regulator. The linear regulator thus operates at relatively low current and duty cycle to limit power dissipation therein. By matching impedances and increasing the bandwidth of the switching regulator, filter capacitor requirements can be reduced to the point of being met entirely by packaging and/or on-die capacitors which may be placed close to or at the point of load to reduce parasitic inductance, as can the linear regulator.Type: GrantFiled: March 11, 2009Date of Patent: September 1, 2009Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Ming Xu, Yuancheng Ren, Fred C.

Patent number: 7579745Abstract: A rotor is operable to rotate in a rotating direction, and is provided with five teeth that define five slots therebetween at regular intervals in the rotating direction. A pair of arc-shaped magnets surrounds the rotor, and faces each other through the rotor. A value of a circumferential angle between two adjacent slots with respect to an axis of the rotor is defined as a. A value of a circumferential angle between opposite end edges of an inner surface of the magnet in a circumferential direction of the magnet, which faces the rotor, with respect to the axis of the rotor is defined as b. The value of b falls within a range from 23 to 25 when the value of a is assumed as 12.Type: GrantFiled: December 21, 2005Date of Patent: August 25, 2009Assignee: Mitsumi Electric Co., Ltd.Inventors: Kensuke Yamada, Yuuki Takahashi, Masami Ito, Takeo Miyajima

Patent number: 7571598Abstract: Preheating of fuel and injection into a plasma torch plume fro adjacent the plasma torch plume provides for only ignition with reduced delay but improved fuel-air mixing and fuel atomization as well as combustion reaction enhancement. Heat exchange also reduced erosion of the anode of the plasma torch. Fuel mixing atomization, fuel mixture distribution enhancement and combustion reaction enhancement are improved by unsteady plasma torch energization, integral formation of the heat exchanger, fuel injection nozzle and plasma torch anode in a more compact, low-profile arrangement which is not intrusive on a highspeed air flow with which the invention is particularly effective and further enhanced by use of nitrogen as a feedstock material and inclusion of high pressure gases in the fuel to cause effervescence during injection.Type: GrantFiled: May 18, 2006Date of Patent: August 11, 2009Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Walter F.

Patent number: 7566828Abstract: A power source device is provided which is capable of charging a secondary cell in a stable manner even in an environment in which power generated by a solar cell varies due to changes in sunlight intensity and/or ambient temperatures. By power generated by a solar cell module, an electric double-layer capacitor is charged and, by using a charging voltage of the electric double-layer capacitor, a booster-type DC-DC (Direct Current-Direct Current) converter is driven. A charge on/off controlling circuit detects the voltage of the electric double-layer capacitor and, when the voltage exceeds a high level threshold voltage, keeps a charge controlling signal (output signal from a terminal) in an active mode and performs a charge starting operation and, after that, when the voltage of the electric double-layer capacitor reaches a low level threshold value, holds the charge controlling signal in a non-active mode and performs a charge stopping operation.Type: GrantFiled: May 12, 2005Date of Patent: July 28, 2009Assignee: NEC Tokin CorporationInventor: Hiroshi Sasaki

Patent number: 7565163Abstract: The receive power of uplink signals in a CDMA mobile communication system is measured by prohibiting a mobile station from transmitting an uplink signal including a frame over a first channel during a predetermined transmission prohibition period, and measuring a receive power of uplink signals at a base station transmitted from each of the mobile stations located in a cell during the prohibition period. Another method of measuring the receive power includes measuring a first receive power of uplink signals at a base station from each mobile station located in a cell, and measuring each second receive power of uplink signal including a frame only over a first channel transmitted from each mobile station, and then calculating a total receive power of uplink signals excluding frames over the first channel by subtracting respective second receive powers from the first receive power.Type: GrantFiled: April 12, 2006Date of Patent: July 21, 2009Assignee: NEC CorporationInventor: Takayuki Kondo
